The paper evaluates the effectiveness of the electromechanical shock absorber for a subway car based on dynamic quality indicators. To determine them, a method of synthesis of random forced vertical oscillations of a dynamic model of a subway car was developed, which is based on the method of sliding summation taking into account the spectral density obtained when processing the test results of a subway car. Also in the work the technique on definition of indicators of dynamic quality of the metrocar with electromechanical shockabsorbers which is based on modeling of processes of movement of the subway car on a site of a way with casual roughness and definition, by results of modeling, indicators of dynamic quality is created. The study of forced random oscillations of the dynamic model of a subway car showed that the spring suspension based on electromechanical shock absorbers has a significant advantage over the central spring suspension for all quality indicators in the entire range of speeds. The dependence of the average power generated by the shock absorber is established.
